Sorry mate, but I find this type of comment exhausting as well - as I always see posts like this by some when criticism is levelled at a player or coach. By definition a forum will have opinions - not all will be positive and glowing. Smith and substitutions is an issue that has long been discussed here, on social media and podcasts. It's obviously a topic of debate. Except for a tiny minority who think only the likes of Antonio Conte should be coaching Aston Villa, feel the great majority are very supportive of Smith. That does not mean he is perfect and cannot improve.
